How do you update that open source code without network connectivity? How do you securely input long transaction data to sign?

So you proposed a way to be more secure, only to discard it yourself in favor of “just having good security”?
You don’t. It’s not networked. It doesn’t need updates.
In fact, updates are only a risk. You physically remove anything that can allow updates to happen + anything that allows wireless networking.
Then your scheme falls apart as soon as a backwards incompatible update is adopted by the blockchain.
How do you actually use funds like this? I mean, I know this is set aside for later. But if you had an emergency, how fast could you actually spend it?
Trivially. You can simply read the keys on the offline machine with your eyeballs and set up a software or hardware wallet elsewhere to access the account.
